A term that typically refers to a certain aspect of a wine rather than to the wine as a whole, "intense" almost always is used in a positive way. It's used to describe a flavor or aroma that is more obvious or pronounced than the others, as in, "This Amarone has an intense aroma of licorice." If the intensity is too great, try a more pejorative term, such as "overbearing" or "unbalanced." Wine tasters sometimes use the word to describe a wine's overall impression, particularly if it stands out among other vintages.
